Optical Smoke Alarms

Optical smoke alarms, also called photoelectric smoke alarms, 'see' smoke. They have a quick response to visibly smouldering fires (e.g. from foam filled furniture & overheated PVC wiring). They are also particularly good in areas where you can otherwise expect false alarms (e.g. near kitchens). We recommend the use of optical smoke detectors in living rooms, bedrooms and hallways.

Optical Smoke Alarms

Optical Smoke Alarms

Optical smoke alarms, sometimes called photo-electric smoke alarms, are a more recent development than ionisation smoke alarms and do not contain any radio-activite material (in contrast to the ionisation smoke detectors). They are less prone to false alarms from cooking fumes such as burnt toast and can therefore be installed near kitchens (but not in the kitchen). They are also very good at detecting smouldering fires, so we recommend them for bedrooms, lounges and the hallway where smoke from soft furnishings is more likely to be detected.
